A secure, zero-knowledge desktop 2FA authenticator for Windows. Encrypted vault with Neon cloud backup. Open source.

Your TOTP secrets encrypted with AES-256-GCM. Desktop, Android, and PWA — all in sync. Every layer of OtpVault is designed to keep your secrets safe — from encryption to infrastructure.

  OVault – Simple and Local OTP Management for iOS/macOS2024 · ovault.net · ▲24

  OVault is a super simple iOS and macOS app that lets you store and view your OTP codes for two factor authentication. I found that my personal favourite OTP app Authy seemed to be getting worse with each iOS release. Its usability has never been great, and iOS 18 meant that it lost its Home Screen Widget that let me view my OTP codes without opening the app. I decided to switch to another app, then became frustrated that I couldn't easily export my secrets from Authy. Of course I'm sure there are good security related reasons for this, but I didn't want to migrate all my OTPs just to end up…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
